GST Complete understanding of India — 5 levels of tax rates, from receipt to tax verification, refund and business registration

Before the introduction of GST, indirect taxes in India were extremely complex. The problem of 'cascading tax' has become chronic as the central government's Central Excise and Service Tax, each state's sales tax (VAT), and local government-related taxes (Octroi, etc.) are imposed in layers. GST, which went into effect on July 1, 2017, aims for ‘One Nation, One Tax’ by integrating these into one value-added tax system.

3 components of GST

Depending on whether the transaction takes place within the same state or between different states, GST is levied in three levels:

For example, a Korean consumer who bought a laptop (GST assuming a standard tax rate of 18%) at a store in Haryana (Gurgaon) would receiveCGST 9% + SGST 9% = 18%You will see that each is listed as a separate item. On the other hand, if a company in Delhi (Union Territory) sells laptops to Bengaluru (Karnataka), the transaction crosses state borders.IGST 18%Charged as a single item. The total tax rate actually borne by the end consumer is the same in either case.

In addition, some luxury and harmful goods such as cigarettes, automobiles, and carbonated drinks are subject to separate charges.Compensation CessAdditional charges apply. This tax rate varies greatly from item to item, so separate confirmation is required.

India GST has been in operation since its introduction.0%, 5%, 12%, 18%, 28%It is designed with a 5-level tax rate slab structure. This is the result of pursuing a progressive consumption tax that minimizes the burden on daily necessities and imposes high taxes on luxury and hazardous goods. However, since item designation by slab is frequently adjusted at GST Council meetings, the exact tax rate of a specific item must be checked on the official site.

Standard tax slabs and representative items

Slab reorganization continues

GST The committee adjusts the slab of certain items upward or downward at every meeting. In recent yearsDiscussion to reduce 12% and 28% slabs and reorganize around 5% and 18%has continued, and in fact several items have been reclassified. Therefore, the table above isReference for understanding the bigger picturePlease use it only, and be sure to check the specific item tax rate and latest revisions.Official GST portal (gst.gov.in) or CBIC (cbic.gov.in)Check out the latest notification. Especially if you are about to make a large purchase or business decision.Based on time of purchaseIt is safe to check the effective tax rate separately.

Official tax invoices issued in India must includeThe supplier's GSTIN, tax rate, and tax amount are specified as separate items.It has to be. If you know how to read receipts properly, you can avoid double taxation, unfair charges, and counterfeit receipts. If you are a business owner, your input tax credit (ITC) requirements are also determined at this point.

What should be included on a formal GST invoice

• GSTIN of the supplier (seller)— 15-digit business registration number (example: 06AAAAA0000A1Z5)
• Supplier name/address, invoice number and issue date
• Buyer name/address (For B2B, buyer GSTIN is required)
• Item description, quantity, unit price and HSN/SAC code
• tax rate and tax amount— CGST/SGST separately (same week trading) or IGST (weekly trading) separately
• Total supply price and added tax amountMarked separately before and after summation

GSTIN How to read the 15-digit code

GSTIN may seem meaningless, but it is actually a structured number.

• first 2 digits: State code (e.g. 06=Haryana, 07=Delhi, 09=Uttar Pradesh, 27=Maharashtra)
• Next 10 digits: Business owner’s PAN (permanent account number)
• 13th digit: Business serial number registered with the same PAN
• 14th digit: Default 'Z'
• 15th digit: Checksum for error verification

For example, GSTIN07If it starts with , it is a registered business in Delhi;06For businesses in Haryana (including Gurgaon),09is a UP state corporation to which Noida belongs. This number isOfficial GST portal (gst.gov.in) → ‘Search Taxpayer’ → ‘Search by GSTIN’You can check the actual registered business name and its active status by checking for free. Before making large payments such as interior design, moving, or used cars, be sure to check to see if they are a real business.

Issues frequently seen in restaurants and hotels

• Forced service charge: Some stores automatically charge a 'Service Charge' separately from GST, but the official position of India's Central Consumer Protection Agency (CCPA) isService charge is consumer voluntary, not legally mandatory.That is. In case of unfair coercion, you can report it to the National Consumer Helpline (1915) or the consumer protection portal (consumerhelpline.gov.in).
• Misapplication of tax rates: Even for the same food, tax rates may be different for dine-in and takeaway, and hotel-affiliated restaurants may have different tax rates depending on the room rate range.
• unofficial receipt: If a handwritten paper receipt does not have GSTIN, it is not a formal tax invoice and is not eligible for business expense treatment or input tax credit (ITC).

The thing that Koreans most misunderstand is the GST refund. To conclude, India is like Europe and Singapore.It is difficult to say that the system that regularly refunds GST to general tourists is currently in operation.(As discussions on introducing related systems have continued for a long time, be sure to check the official Indian customs and government guidance for the latest implementation). On the other hand, there is a clear path for businesses to recover input tax.

Representative scenarios where refunds are possible

1. Input Tax Credit (ITC)— GST paid by a registered business corporation or individual business owner for raw materials and services purchased for business purposes is offset (deducted) from GST received at the time of sale. In fact, it is the most common form of 'refund' and is only recognized when the official GST invoice and the supplier's GSTR-1 report match (reflecting GSTR-2B).
2. Export Transactions (Zero-rated Supply)— GST 0% is applied to exported products, but GST paid when purchasing raw materials remains. There are usually two ways to retrieve it.
   ① After submitting the LUT (Letter of Undertaking), export tax-free and apply for a separate refund of input tax.
   ② Export after paying IGST and apply for refund of the full amount of IGST paid
3. Excess Payment— GST overpaid by a business operator by mistake, the remaining tax amount arising from a corrected return, etc. are subject to an official refund application.
4. Special provisions for embassies and international organizations— Foreign embassies, UN organizations, etc. that have entered into agreements with the Indian government can claim purchase GST refund in a designated manner. For information on procedures for individual diplomatic status, please contact the general affairs team of your embassy.

What the average consumer will remember

• not a businessThere is no regular system for individual consumers to individually refund the GST they have already paid.It is more accurate to look at it this way.
• However, in online shoppingIf an order is canceled or returned, the entire payment amount (including GST) is automatically refunded.Therefore, a separate application is not necessary.
• When purchasing high-value assets (cars, home appliances, moving, etc.), check whether the tax rate is applied correctly and whether GSTIN exists.check in advanceThis is much more efficient than the post-refund process.
• Purchases made at airport duty-free shops are originally sold with tariffs and GST exempted, so they are not refunds but rather ‘duty-free sales.’

If you are a Korean who runs a business or maintains a freelance contract in India, GST business registration becomes mandatory at some point. Voluntary registration is also possible, but as the business scale increases, obligations automatically arise, so it is important to know the standards in advance.

Typical situations in which registration obligations arise

• If annual sales exceed a certain threshold — this threshold isIs the product/service a special category for the state in which it is located?It applies differently depending on the conditions, so you must check the official site for the latest standards. (As of the time of introduction: annual sales of ₹40 lakh for product suppliers, ₹20 lakh for service providers, and half of each in special category states, but there is a history of frequent revisions)
• Regardless of salesInter-state supplyIf you do

To summarize what has been said so far from a real-life perspective, it is as follows. As consumers and business owners, the points at which Koreans encounter GST in India are not very different, but there are different points to keep in mind.
